iPENCIL-ZPRINTING MACHINE.

T 0 all whom it may concern: I

Be it known that I, HARRY W. BREWER,

a citizen of the United States, residing at. -Hutchi11son,in the county of Reno and State of Kansas, have invented certain new and useful Improvements in Penc1l-Ir1nt1ng Machines, of WlllCll the following 1s a speclfioainvention relates to pencil printing machines, and embodies means for printing one or more colors upon a pencil, or the like.

In order that the invention may be fully understood, reference will nowbe made to the accompanying drawings, in which:

Figure 1 1s a'plan vlew of my machine.

Fig. 2 is a side elevation of -t-l1e--machine. Fig. 3 is a cross section on line III--III of Fig. 1. Fig. 4 is an irregular longitudinal section on line IV-IV of Fig. 1,and Fig. 5 is a detail of a lever and pawl to actuate one of the inking-disks of the machine.

In carrying out my invention I employ a frame 1, each side of which is provided at its inner side with a pair of longitudinal rails 2, traversed by a reciprocatory carriage 3, actuated by a crank-shaft 4 through the intermediacy of a connecting-rod 5, pivotally-secured at its forward end to a pair of arms 6, secured at their forward ends to opposite sides of carriage 3.

7 designates a support carrying at its underside plural sets of type, symbols, or other printing means, for printing the pencils in one or more colors. In the drawing I have shown two sets of type 8 and 9. Support 7 is pivotally-mounted at its ends upon a rod 10, so that it may be swung upward to gain access to the type at the underside thereof, but is normally held downward in printing position by a pair of links 11, pivotally- "secured by bolts 12 to the outer sides of frame 1. Rod 10 is carried by a pair of brackets 10 secured to the opposite sides of frame 1. Links 11 have lugs 13 upon which the adjacent side of the support 7 is reliably-held 'n printing position by set-screws 14, extending down through the upper por tions of the links.

15 and 16 designate rotatable inking-disks supported by two transverse bars 17 and 18, respectively, which assist in uniting the sides of frame 1. The inking- disks 15 and 16 are provided at their undersides with circular rows of ratchet- teeth 19 and 20, respectively,

teeth 19 being reversely-disposed to the teeth 20, so that the inking-disks will be alter- Specification bf Letters i'atent.

nately rotated step by step as will hereinafter appear.

21 and 22 designate a pair of gravity.

nal 33 engaging the opposite sides of an eccentric 34, fixed upon one end of crankshaft 4, wh-1ch latter is provided at its opposite end with a drive pulley 35.

36 designates two ink-distributing rollers journaled in the forward end of carriage 3 to stake ink from the inking-disk 15 and distribute the same upon the type 8; and .37 designates two ink-distributing rollers for 'taking ink from the inking-disk 16 and distributing the same upon the type 9.

.38 designates two pairs of disks for carrying the pencils into and out of engagement with the type 8 and 9, a pencilA being shown in position upon said disks, in Fig 4. Disks 38 are mounted upon two shafts 39, journaled in the opposi e sides of the carriage 3, which opposite sides are united by a pair of braces 40 Disks 38 are adjustably secured to shafts 39, so that the disks on each shaft may be moved toward or away from each other to accommodate pencils of different lengths, care being taken, however, not to set the disks close enough together to come into contact with and blur the printed portions of the pencils.

41 designates a .pair of rockingly-mounted unloading arms for lifting the printed pencils from the disks .38 and depositing them 11 on a runway 42, which conducts the penclls to any desired point. Arms 41 are adjustably secured to a shaft 43, so that they may be adjusted toward or away from each other with the disks 38, to accommodate pencils of different lengths. Shaft 43 is mount-' led in a pair of bearings 44 and provided near one end with a crank-arm 45, rocked up and down intermittently by a vertically-arranged stem 46, actuated by a spring 47 and a cam 48, which latter is fixed upon one end of a stub-shaft 49, journaled in one side of frame 1 and provided at its opposite end with a bevel gear 50, intermeshing with a bevel gear 51 fixed upon one end of a shaft 52, journaled in a bearing 53 and provided at its opposite end with a bevel gear 54,

riage to the position shown in Fig. 4, saidpencil will'be carried into and out of contact with the two sets of type 8 and 9, which print the pencil in different colors. As the pencil contacts with type 9, it is rotated thereby and presents a difi'erent surface to the type 8, so that the same will not obliterate the printing performed by the type 9.

-. As the carriage 3 approaches the rear end of its movement, the pencil is brought into position over the curved terminals of the unloading arms 41, the actuating mechanism of which is so timed as to cause said arms to lift the pencil from the disks 38 before the carriage moves backward. When the free ends of the unloading arms 41 move upward a certain height, the pencil rolls "downward off the same onto the runway 42, which, as hereinbefore stated carries it to any desired point. As the inking- disks 15 and 16 have been supplied with different colored inks, a portion of the ink from disk 15 is taken up for type 9 by the distributing-rollers 37 at each forward movement of the carriage 3,

- and a portion of the ink is taken up from disk 15 for type 8, by the distributing rollers 36 at each rearward movement of the carriage, the movement of the carriage being of such length that the upper roller 37 is not brought into contact with the type 8,

Spring 47 is inter posed between guide 56 and the yoke 58 car- V timed with relation to the movement of the V carriage 3, that it will actuate disk 15 when the lowermostink-distributing, roller 36 is.

out of engagement therewith, and: actuate disk 16 when the lowermost ink-distributing roller 37 is out of engagement therewith, and although the pawls 21 and 22 are simultaneously actuated by their respective levers 23 and 24, when one of said pawls positively engages the ratchet teeth of its respective inking-disk, the other pawl idly slides overinto'and out of engagement with said print-I mg means, and unloading arms to lift the pencil from said disks.

2. In a machine of the character described, stationary printing means for printing one or more colors on a pencil, or the like, movable means to carry said pencil into and out of engagement with said printing means, rockingly-mounted unloading arms to remove the printed pencil from said movable means, and means timed with said movable means to actuate the unloading arms.

3. In a machine of the character described, printing means for printing one or more colors on a pencil, or the like, movable means to carry a pencil into and out of engagement with said printing means, rockingly-mounted arms to remove the printed pencil from said movable means, a stem for actuating said arms, a guide through which said stem extends, resilient means for moving said- In testimony whereof I aflix'my signature, I
